SWING.

SPECIFICATION formingpart of Letters Patent No. 642,673, dated February6, 1900.

I Application filed August 17, 1899. Serial No. 727,551. (No model.)

T0 at whom it may concern:

Be it known that I, JOHN G. BRENNER, of Toledo, county of Lucas, andState of Ohio, have invented certain new and useful Improvements inSwings; and I do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the characters of referencemarked thereon, which form part of this specification.

My invention has reference to a swing, and is adapted to be used inpublic parks, public playgrounds &c.

I Myinvention is not designed for use alone by children, but isespecially adapted for elderly people; and with this object in view itis constructed to combine the factors of comfort and safety.

In carrying out my invention I provide a chair suspended from a suitabletrestle and having a tiltingseat and back and a footboard which servesas an anchor for the swing when the person about to enter the chairsteps thereon and which raises automatically when the person is seated.

My invention further embodies certain novel features of construction andthe parts and combination of parts hereinafter shown, described, andclaimed.

In the drawings, Figure 1 is an elevation of my invention, showing thechair suspended from the trestle, also showing the footboard in alowered position in contact with the ground to anchor the chair. In thisview the legs of the trestle and the straps by which the chair issuspended are shown cut away because of limited space upon the sheet.Fig. 2 is an isometric view showing the means of attachment of thestraps which support the chair.

The trestle upon which the swing is hung is formed of twoinverted-V-shaped supports, composed of pieces 1 and 2, arranged a shortdistance apart to permit the chair 3 to swing between them. Pieces 1 and2 are bolted together at their upper ends at 4. and are spread apart attheir lower ends to give stability to the trestle. Near the upper endsof pieces 1 and 2 are secured pieces 5, which support a cross-piece 6,through which pass bolts 7, having bifurcated heads 8, adapted toreceive the ends of straps 9. After the straps 9 have been inserted intothe bifurcated heads 8 they are securely fastened by passing rivets 10therethrough. Straps 9 may be made of wood; but I prefer to constructthe same of metal and preferably of steel. The lower ends of straps 9are secured to bolts 11, similar in all respects to bolts 7. The frameof the chair is composed of two similar segmental circular side sections12, to which bolts 11 are secured, the brackets 13, the arm-pieces 14:,joined to the standards 16, and the seat-frame 15, extending between thestandards 16 and the side sections 12. The ends of sections 12 aresecured together by rod 17, having interposed intermediate of its lengthan ordinary turnbuckle 18, by which means the circularity of sections 12is maintained. 19 is the chairback, pivotally connected to parts 13 at14 and having a coiled spring 20 attached to the upper end thereof,which is also attached to section 12 at-20. The seat of the chair 21 ispivotally connected to seat-frame 15 at 22 and is connected by a link 23to a piece 24, pivoted at 25 and having on the end thereof the footboard26.

I wish it to be understood that in this description where reference ismade to the parts on one side of the chair the other side is alsoreferred to, as both sides of the chair are identical in construction.

When a person is about to enter the chair, he steps upon the footboard26, causing it to take its normal position in contact with the ground,as shown in full lines, Fig. 1. The footboard while in this positionwill securely anchor the chair against movement and overcome the usualdanger of the moving parts of the swing striking the shins of theperson.

After the person has seated himself the seat of the chair will take theposition a, (shown in dotted lines, Fig. 1,) which will cause thefootboard, through the medium of the connecting-link 23, to rise fromthe ground and permit the free movement of the swing. This movement maybe imparted to the swing by a person standing behind the same, or a ropev(which I have not deemed necessary to be shown in the drawings) may beattached to the legs 1 and 2, respectively, of the trestle in convenientreach of the person seated in ICC the chair. By means of theconstruction which I have described the back of the chair will assume avariable position Z), (shown in dotted lines, Fig. 1,) which, togetherwith the variable seat of the chair, will conform to any angularposition which the body of the person seated in the chair may assume.

I wish to lay particular stress upon the practical method which I employto suspend the chair from the trestle. By employing metal straps, whichby their resiliency permit the chair to swing, and the bifurcated bolts7 there is no Wear whatever at the point of attachment. I wish also tomention the practical construction of my chair. By forming the frame of'two segmental circular sections and having all other parts of the chairdepend therefrom I furnish an extremelyrigid construction andpractically insure the chair from coming apart through exposure toweather.

II'aving described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. In a swing, the trestle, the chair suspended therefrom, having thesegmental circular side sections, the seat-frame supported thereby, thetilting seat movably secured in the seat-frame, the movable footboardpivotally attached to the side sections, and a link connection betweenthe footboard and the seat, substantially as and for the purpose setforth.

2. In a swing, the trestle, having the crosspiece 6; the chair havingsegmental circular side sections 12, the adjustable back 19, the
